Wikipedia:Content policy in a nutshell

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

Articles appropriate for this encyclopedia, cite verifiable claims from reliable sources (in proportion), without presenting our own claims.


Claims should come from published sources that can be verified by other Wikipedia editors.

Wikipedia:Reliable sources[edit]

Verifiable claims should be based on references released by established experts and/or publishers with editorial oversight that have a reputation for fact-checking and accuracy.

Wikipedia:Citing sources[edit]

Citing verifiable reliable sources is necessary for editors to verify the claims and assess the reliability of the references.

Wikipedia:Neutral point of view[edit]

Wikipedia articles should present the claims and opinions appearing in the published body of reliable sources, in proportion to their prominence.

Wikipedia:No original research[edit]

Claims must be verifiable in reliable references; consequently, editors may not insert their opinion or analysis of a subject into Wikipedia articles, explicitly or through presentation.


Wikipedia articles require enough reliable independent sources to justify a complete article. There are subjects that possess enough sources to build some kind of article, but what Wikipedia is not still applies.
